In the case of working with integers or non-interval measures, the lower weighted median would be accepted since it is the lower weight of the pair and therefore keeps the partitions most equal. However, it ... WebThe filter can also be applied to only a ROI. This is recommended for filters which are cost intensive, like the “Gaussian Weighted Median”. The parameter setting is only needed for the “Bilateral Filter” (range radius) , “Mean Shift Filter” (Color Distance) and the “Linear Kuwahara” (line length). Filter_Check.png.
